How to solve the problem of transportation and storage of picric acid explosives, this matter is difficult for others, and it will definitely be difficult for Zhu Youxiao.

Because this matter has been a secret that has been revealed in the afterlife. Of course, in the era of the Ming Dynasty, it is impossible for anyone to know.

This secret is actually very simple to tell. In fact, a lot of technology is not figured out, and sometimes it's just simple.

There are many examples that tell everyone that it is such a simple secret, and sometimes it can lead to a war, or even a war that lasts for many years.

The secret was to paint the inside of the shell and attach a thick layer of paraffin wax to isolate the picric acid from direct contact with the shell of the shell, and solve the big problem in such a simple, ingenious and inexpensive way.

Although the paraffin wax will fall off over time, making it impossible to store picric acid explosives for a long time, but at least it can be used.

And, as a large number of consumables, can shells be stored until the day the paraffin comes off?

For Japan at that time, their national strength was weak and their output was very small, so they had to use their brains in many ways.

This ingenuity gene also carried over to the design of the later Type 38 rifle, and a dust cover solved the problem of the rifle isolating sand and dust.

Now Zhu Youxiao just took it and used it, which is also suitable for the current productive forces.

Picric acid is simple to manufacture, low in cost, and good in power, which solves the problem of transportation and storage, so naturally there are no other problems. This is a very good gunpowder, which is just used to make metal shells.

This gunpowder, invented by the French, eventually came to fruition in Japan. In fact, the French also knew that this thing was very important, so they only wanted to sell the finished product to the Japanese, and did not want Japan to study it themselves, let alone give it to the Japanese production line.

But the Japanese are not in vain, and when I visited the French factory, there was a man named Tomioka Dinggong.

Tomioka was humble and studious at that time, carefully pinched a pinch of picric acid crystal granules and kneaded them, looked carefully with his eyes, put them on his nose to smell, carefully felt the feeling with his hands, almost put it in his mouth to taste it, and then put it back as if nothing happened.

Back at the Japanese delegation's residence, Tomioka carefully plucked a small piece of picric acid powder from his fingernails. In September 1888, the precious powder was finally handed over to Masahiro Shimose, a master of the Naval Ordnance Factory.

It was such a little bit of powder that was finally studied by the Japanese, and was used and conquered by Japan, and became the famous inferior gunpowder later.

And its birthplace Europe, because it could not solve the problem of transportation, instead conquered the more powerful nitroglycerin explosives, made high-precision and more stable, picric acid explosives were eliminated from history.

With the current strength of the Ming Dynasty, it is too difficult to make nitroglycerin explosives; Instead, it is a picric acid explosive, which can be produced in large quantities.

Zhu Youxiao had known about this matter for a long time and got the report. It's just that he didn't expect Bi Maokang's progress to be so fast, not only made metal fixed artillery shells, but also made mortars.

Looking at the posture next to it, there should be heavy artillery over there.

Zhu Youxiao couldn't help but stand up, looked at Bi Maokang and said, "Since it's ready, let's put a few shots and try it and see how it works." ”

After hearing this, Bi Maokang naturally didn't dare to slack off, and hurriedly said, "The minister will arrange it immediately." ”

"Go, go, go." Zhu Youxiao nodded and said.

In fact, Bi Maokang is going down to get ready to make arrangements. If you don't arrange it, this test was originally an internal test, and everyone's attitude is still very relaxed and harmonious. With the attitude that even if you fail, it doesn't matter. After all these years, they have not failed.

But this is not the case now, and now His Majesty is here. Who would have thought that His Majesty would come here at this time?

When they get here, His Majesty wants to see them experiment, and if something messes come up, it will be bad.

If the experiment can be done successfully and His Majesty can see the effect, it will naturally be a good thing.

Bi Maokang hurriedly arranged it, and at the same time explained what he had to do, so that his subordinates could use a little more heart and never make any mistakes. Strive for a success, so that His Majesty will be happy to watch.

What Bi Maokang went to do, of course Zhu Youxiao knew, but he didn't stop it.

After being an emperor for such a long time, Zhu Youxiao knows one thing very well, that is, you have to give your subordinates a chance to perform, and you can't let them have no chance to perform. Then, when they behave, give them some appropriate rewards, praise and praise them.

Something like this is important to them, and this sense of honor is important to them. So Zhu Youxiao not only did not stop it, but encouraged it, and sat there quietly to show that I was looking forward to it.

Soon, Bi Maokang arranged things.

Although Bi Maokang went to arrange things, the current situation did not allow him to do it for too long. After all, you can't let Your Majesty wait here for a long time.

Bi Maokang soon returned, and he said, "Your Majesty, you are ready. ”

"Okay, then come on." Zhu Youxiao nodded and said excitedly.

Taking the telescope from Wei Chao's hand, Zhu Youxiao sat and waited excitedly.

As for looking closely, Zhu Youxiao didn't mention it at all. The reason is very simple, it is impossible for his subordinates to let him go, and it is just a matter of.

And the mortar thing has just been figured out now, and the danger is very high, maybe there will be an accident.

Don't join in the fun at this time. If you blow yourself up, the consequences will be serious.

For his own life, Zhu Youxiao attaches great importance to it. He didn't live for himself, he couldn't have any problems.

Bi Maokang naturally didn't know what the emperor was thinking, he wanted to behave well now.

He was very excited in his heart, and waved the flag of the herald, so that the people below were ready to fire.

And at this time, people in the distance also moved.

They worked in pairs, carrying a wooden box in their hands, and went directly to the mortar.

Then they opened the box, took out the shells inside, and carefully held them in both hands.

After seeing this scene, Zhu Youxiao's face was excited.

Finally see something with a tail fin behind this shell!

After seeing this thing, Zhu Youxiao was so excited that he couldn't help himself.

Good stuff, good stuff!

Zhu Youxiao was a little impatient to see the final results of the experiment.

After taking out the shells, these people began to use their fingers to complete the positioning, and quickly adjusted the angle of fire.

The last man held the cannonball and put it directly into the muzzle, and as soon as he let go, the cannonball fell directly into the barrel, followed by a bang.

Zhu Youxiao watched the cannonball spin and fly out in the telescope, and then fell fiercely on the ground not far away.

With a "boom", the shell exploded in an instant.

After seeing this scene, Zhu Youxiao couldn't help but stand up excitedly.

Bi Maokang, who was beside Zhu Youxiao, jumped up directly and happily, and shouted loudly: "It's done!" It's done! ”

Obviously, Bi Maokang was also excited, and he couldn't help it.

After a while, Bi Maokang came back to his senses, and hurriedly saluted Zhu Youxiao and said, "Your Majesty, the minister is too excited. If you lose your honor in front of you, please ask Your Majesty to punish you. ”

Zhu Youxiao glanced at Bi Maokang, and he didn't know what he meant by acting.

But it doesn't matter, as an emperor, you have to put up with this.

Zhu Youxiao said with a smile: "Aiqing has worked hard to make such a good thing for Daming, and has persevered for so long. Now that the thing is done, Aiqing naturally has to be happy. I will write down your merits, and I will definitely reward you well. ”

"Thank you, Your Majesty!" Bi Maokang hurriedly said, with a bright smile on his face and a very excited tone.

Isn't what Bi Maokang said just now just to let His Majesty reward himself well? He has his own ideas. Now that His Majesty says so, it is natural that everyone will be happy.

"Let them put it again." Zhu Youxiao looked at Bi Maokang and said, "Look at the power." ”

Naturally, this thing can't just be fired, even if it's an experiment, it can't be just one.

So the experiment began again, this time with a dozen guns fired together.

Looking at the dust bombed from the opposite side, Zhu Youxiao was happy.

This is what the meaning of artillery is, what was the previous artillery called?

However, Zhu Youxiao did not interfere later, and the test of this kind of thing has an overall process. Test the strength and check where there is a problem, these things are not something that Zhu Youxiao can interfere with.

If you just fire a few more cannons for the pleasure of your own emperor, maybe you will blow up later. Zhu Youxiao naturally wouldn't do this kind of thing, after all, everyone here is his baby, and killing one or injuring one is a great loss for him or Daming.

Bi Maokang arranged for people to continue the experiment, to what extent the gun tube will not be able to withstand it, and to what extent it will affect the degree of hair, in short, all the tests are carried out one by one.

But this kind of thing doesn't need to be accompanied by Zhu Youxiao

Bi Maokang took Zhu Youxiao to another testing ground.

Here, Zhu Youxiao saw artillery.

Unlike the previous guns, this was a rear-loading metal cannon that used metal fixed shells. And from the perspective of styling, this thing is the famous Miss France, which has a more familiar name in later generations - Italian cannon.

This gun is a French M1897 75mm gun, developed in France in 1897. Because it was the world's first gun equipped with an anti-recoil device, the rate of fire of the gun was as high as 15 rounds per minute, far exceeding that of other artillery of the same era, so it shined in the First World War, with more than 20,000 units produced and sold.

During the First World War, Italy used to make a lot of this artillery. After the end of World War I, they exported the obsolete artillery to China at that time. Because the cannon has a lot of Italian characters on it, this cannon is called Italian cannon in China.

This thing was actually very famous in China, but it was actually not the best artillery of the time. After all, at that time, there were many places in the country where artillery could be made.

The Jiangnan Manufacturing Bureau Gun Factory in Shanghai is already capable of producing artillery of the same caliber and technical level.

In 1905, the successful imitation of the Krupp 14 times 75 mm mountain gun, basically realized the national production of parts, and a total of nearly 500 pieces were produced.

Even some far-sighted local warlord-dominated arsenals produced larger-caliber and more advanced artillery, such as the Shenyang arsenal of the Feng warlord Zhang Zuolin, which produced 100-mm, 105-mm, and even 240-mm heavy howitzers.

The Taiyuan Arsenal of Shanxi warlord Yan Xishan also produced 75 mm and 88 mm mountain artillery field guns.

It's just that since the September 18 Incident, the domestic arsenal has shrunk seriously, and the ability to make artillery has declined significantly. There should have been better artillery, but by this time there was none, making this kind of Miss France, which was about to be eliminated, a very scarce thing.

But in the era of the Ming Dynasty, the Italian cannon was naturally extremely advanced, after all, this is a classic, and many light guns in later generations were modified on this basis.

Just like the AK47's firearms, it has developed into a gun family. But when everyone mentions this series, it's still AK47.

Among the rear-loading artillery, Miss France is a hurdle that cannot be bypassed. Just like among the bronze cannons, the Napoleonic cannon is a hurdle that cannot be bypassed.

So after the first artillery of the Ming Dynasty was finalized, it was this kind of French lady.

Zhu Youxiao looked at Bi Maokang with an excited look on his face, but he turned his head and asked with a serious face: "Can it be done?" If not, don't be in a hurry. ”

Regarding the issue of artillery rifling, this has long been resolved. Daming's progress in this area is still very fast, and the barrel alloy material of the artillery is well solved, although some copper is still used, but it is very little. It's just that in terms of cannonballs, copper still needs to be used in large quantities.

It's just that Zhu Youxiao is worried about the artillery itself, don't bomb it again if it is unsuccessful. Zhu Youxiao doesn't ask them to go up quickly, after all, the Ming Dynasty is still quite peaceful now, and it takes a lot of money to make large-scale production equipment.

To be honest, Zhu Youxiao XZ has no money. The money that the internal government is taking out now is just enough for expenses.

Harvesting grain every year for disaster relief makes Zhu Youxiao very big. Trade profits in the northwest have also begun to shrink, after all, those Mongolians have not had a good life in the past two years, and there is no surplus food in their homes.

In other respects, Zhu Youxiao's income is very small. The income of the household above the court, not to mention.

In the past few years, Zhu Youxiao has just equipped all the pro-army with flintlock pistols, rocket launchers, and hand-cranked light machine guns. Now if Zhu Youxiao changes their clothes again, to be honest, they are a little weak.

What's more, there are shipyards in Qingdao, which makes Zhu Youxiao feel a little distressed to burn money.

So now this thing is really not in a hurry, there is no need to be on it. Zhu Youxiao can afford to wait.
